In an organization, we were working through a contractor. We engaged in the main production activity, and the principal employer appointed only a production manager; no other worker is engaged through the principal employer. Now, the principal employer wants to shut the plant for renovation. We are all permanent workers of the contractor. The principal employer is saying we are not their workers, so they have nothing to do with us. Now, our contractor wants to either settle with us or transfer us to other states. Can we insist that the principal employer continue to employ us as the factory is going to restart after renovation?
